A set of doodles based on the question "why should a flying car look like a road car?"
Ditched the ducted fans on the assumption that the car uses an antigravity lifting engine and some sort of reactionless drive; this way you get to keep the sleek lines.
For neatness, I think the antigrav and drive will be under the floor; therefore the next pic needs a thicker underfloor. Also, windscreen wipers seem a bit off for the high tech aesthetic, so I think self-cleaning super-hydrophobic glass is indicated for the windscreen.
